Maryport's new walkway

This short piece of walkway joins two walking routes in Maryport and we thought it was time we went to see it There was a lot of local publicity about it and I must admit that we were expecting a bit more of it (We are not alone in this!)
The other shot is of the well-known sculpture blipped by Trev today. Does anyone know about the stone ribs which you can see in the mud in the river bed.
